Nanotechnology
The purification processes based on nanotechnology are thought to be highly efficient and cost-effective. Nanotechnology encompasses a variety of methods and processes for applying materials at the atomic or molecular level. As compared to traditional water purification methods, nanotechnology-based water purification processes are thought to be scalable, highly functional, and cost-effective.
Silver, copper, and zero-valent iron (ZVI) nanoparticles, nanostructured photocatalysts, nano-membranes, and nano adsorbents are some of the main applications of nanotechnology in water treatment processes.
The high surface-to-volume ratio of nanoparticles improves the adsorption of chemical and biological particles, thus allowing pollutants to be separated at very low concentrations. Nanoadsorbents have unique physical and chemical properties that enable them to remove metallic contaminants from water.
Acoustic Nanotube Technology
Acoustic nanotube technology was developed by Nasa scientists at the Johnson Space Center. It directs water through small-diameter carbon nanotubes using acoustics rather than pressure.
The technology is based on an acoustically driven molecular screen that is integrated with carbon nanotubes and allows water molecules to move while blocking larger molecules and pollutants. It uses less energy than conventional filtration systems and directs water away from pollution rather than removing pollutants from water. The method also removes the need for the filter system to be flushed.
